Abstract:
Tensor interpolation is an essential step for tensor data analysis in various fields of application and scientific disciplines. In the resent work, novel interpolation schemes for general, i.e., symmetric or non-symmetric, invertible square tensors are proposed. Critically, the proposed schemes rely on a combined polar and spectral decomposition of the tensor data T =RQTΛQ, followed by an individual interpolation of the two rotation tensors R and Q and the positive definite diagonal eigenvalue t...     »
